C#: Display the pattern like a diamond

C# Sharp For Loop: Exercise-31 with Solution

Write a program in C to display the pattern like a diamond.
The pattern is as follows :

      * 
     *** 
    ***** 
   *******
  *********
   *******
    *****
     ***
      *

Sample Solution:-

C# Sharp Code:

using System;  
public class Exercise31  
{  
    public static void Main()
{
   int i,j,r;
   
	Console.Write("\n\n");
    Console.Write("Display the pattern like diamond:\n");
    Console.Write("-----------------------------------");
    Console.Write("\n\n");     
   
   Console.Write("Input number of rows (half of the diamond) :");
   r = Convert.ToInt32(Console.ReadLine());   
   for(i=0;i<=r;i++)
   {
     for(j=1;j<=r-i;j++)
     Console.Write(" ");
     for(j=1;j<=2*i-1;j++)
     Console.Write("*");
     Console.Write("\n");
   }
 
   for(i=r-1;i>=1;i--)
   {
     for(j=1;j<=r-i;j++)
     Console.Write(" ");
     for(j=1;j<=2*i-1;j++)
       Console.Write("*");
     Console.Write("\n");
   }
  }
}

Sample Output:

Display the pattern like diamond:                                                      
-----------------------------------
Input number of rows (half of the diamond) :8                                                                                                         
       *             
      ***                           
     *****                           
    *******

  ***********                     
   *********                        
    *******                  
     *****
